But countries seeking fresh gas supplies could do far worse than fracking. So say Duke University researchers who, in today’s issue of the research journal Nature Climate Change, shine a jaundiced spotlight on China’s plans to synthesize natural gas from coal. Nine synthetic gas plants recently approved by Beijing would increase the annual demand for water in the country’s arid northern regions by over 180 million metric tons, the Duke team concluded, while emissions of carbon dioxide would entirely wipe out the climate-cooling impact of China’s massive wind and solar power installations.

The Arctic is melting faster than predicted. Is now the time to shut down the low-carbon nuclear power plants in France — the 20th Century’s staunchest proponent of nuclear energy? Is natural gas produced via hydraulic fracturing or ‘fracking’ a gift that is buying time for a transition to renewable energy or a curse that reinforces fossil fuel dependence? Will carbon belching heavyweights such as the U.S. and China ever get serious about cleaning up their energy systems?
Such questions are top order in France, whose President kicked off a Grand Débat on energy this month Continue reading →
India’s Koyna Dam: The textbook case for induced seismicity
Fracking for natural gas, whereby gas-trapping rock formations are blasted open with high-pressure water and chemicals, has prompted serious concerns over the safety of groundwater supplies. But another risk is gaining profile: the potential for inducing nerve-rattling microseismicity or, potentially, unleashing a quake of truly destructive magnitude. Like the magnitude-5.6 quake that rocked Oklahoma last weekend.
Heckled and booed off the stage at a series of public meetings earlier this month, Quebec’s salesman-in-chief for a novel energy development withdrew from the fight this week – citing the advice of worried doctors but vowing to rejoin the fight. The inspiration for André Caillé’s intemperate welcome was not a coal-fired power plant or a pipeline full of heavy oil from Alberta’s tarsands, but what until recently was considered the green fossil fuel: methane.

The problem with Bloom Energy’s Bloom Box stationary fuel cell is that, despite 60 MINUTES’ assertion that it might be the holy grail to free Americans shackled to a coal-fired grid, the company has yet to deliver a product. Moreover, the technology is hardly new. Continue reading →
Benjamin Sovacool agrees that wind turbines kill birds and bats, but this University of Singapore public policy professor makes a convincing case that this fact desperately needs context. Reviewing avian mortality from power generation in the June issue of Energy Policy, Sovacool shows that — gigawatt-hour for gigawatt-hour — it is fossil-fired power by a longshot that will ground winged creatures.
Sovacool’s analysis estimates avian deaths throughout the fuel cycle for coal, oil and natural-gas fired power generation:
Coal mining = 0.02 deaths per gigawatt-hour (GWh). For example, habitat destruction by mountaintop removal coal mining in Appalachia has killed approximately 191,722 Cerulean Warblers.
Plant operations = 0.07 bird deaths/GWh. Electrocution at one well-observed power plant in Spain killed 467 birds over two years.
Acid rain = 0.05 deaths/GWh. Cornell’s Laboratory of Ornithology estimated in 2002 that acid rain reduced the U.S. wood thrush population by 2–5%.
Mercury emissions = 0.06 deaths/GWh. Impacts include hampered reproduction and survival, observed in everything from albatross and woodstorks to bald eagles. Continue reading →
The head of the Federal Energy Regulatory Commission (FERC) predicts that plug-in hybrid vehicles will provide immense benefit to power grid operators — enough for utilities to provide kickbacks to their customers, paying down the extra cost of a plug-in in as little as three years. Jon Wellinghoff, FERC’s acting chairman, made that comment at a Las Vegas trade show last week according to coverage by the Las Vegas Review-Journal (which I picked up on thanks to the keen newswatching eyes of specialty publication EV World).
Wellinghoff’s comments refer to plug-in hybrids equipped with the smarts to communicate with the power grid, which he termed the “Cashback Hybrid” according to the Review-Journal article:
When the Cashback is plugged in, motorists can allow the utility to vary the speed at which the battery recharges so that the utility can more closely match supply and demand for power on the electric grid…In return, the car owner could obtain cash back or a credit from the utility that makes the electricity free, he said.
